Cross-Platform App Development in Berkeley: challenges we solve
Ideas don’t scale.
Products do.
We turn raw concepts into fully functional apps that work across platforms from day one.
One team, one codebase,
full coverage — with performance that feels native, everywhere.
Design breaks between platforms.
Shared components built.
Edge cases resolved.
Features lag behind across versions.
Native quirks handled.
Stability aligned.
App crashes on one OS,
not the other.
Touch-first UX mapped. Navigation rebuilt.
User flows feel clunky
on mobile.
Codebase unified.
Update cycles synced.

FAQ

Why choose cross-platform for Berkeley businesses?
Berkeley's audience spans every device — iPhones in Claremont, budget Androids among international students, tablets in research labs. Building natively for each platform doubles cost and timeline. Cross-platform frameworks ship one codebase to both stores, reaching all Berkeley users without compromise.
How long does cross-platform development take?
A focused app reaches both iOS and Android in 3-5 months simultaneously. Compared to two native apps, you save 30-40% on timeline. Berkeley startups use this efficiency to collect feedback from UC's diverse device ecosystem at once, accelerating product-market fit.
What affects cross-platform app costs?
Feature complexity, native module requirements, backend infrastructure, and design depth drive pricing. A campus utility app costs less than a real-time research platform with maps, camera, and offline sync. The real saving is ongoing — one codebase means fixes ship to both platforms simultaneously.
React Native or Flutter for Berkeley projects?
React Native if your Berkeley team knows JavaScript/React — skills transfer directly and Bay Area hiring is easier. Flutter for better animation performance and consistent cross-platform look. We recommend based on your team's expertise, hiring plans, and specific feature requirements.
Are cross-platform apps as good as native?
For 90% of business applications — yes. UI, networking, storage, maps, cameras, and push notifications perform at near-native levels. Berkeley users won't notice the difference in delivery apps, campus tools, or business applications. Only hardware-intensive apps truly require native.
Can cross-platform apps access device features?
Yes. Camera, GPS, push notifications, biometrics, file system, and Bluetooth are accessible. For Berkeley research apps, GPS tracking and background location work reliably on both platforms. Platform-specific bridge code handles rare native-only APIs.
How do you test across platforms?
Physical iOS and Android devices representing Berkeley's actual user base. Automated tests on both platforms every code push. TestFlight and Play Store test tracks deploy simultaneously for side-by-side team review.
What ongoing support?
Apple and Google OS updates, framework upgrades, dependency maintenance, and features. One codebase means unified support — fixes ship to both platforms at once. Berkeley businesses get single maintenance retainers instead of managing two separate app codebases.
